Ob NEUROPTERA. 



elougatus, Steph. 111. 227, 45 (?) ; L. fuliginosus, 

 Steph. 111. 227, 46(£); L. ustulatus, Steph. 111. 

 228, 47 (var.) ; P.Jiava, Pict. ; L. nebulosa, Ramb. 



Qchreous ; antenna?, head and thorax somewhat red- 

 dish ; the anterior wings have a brown dash from the 

 apex to the anastomosis, and another along the whole 

 posterior margin, the two being sometimes connected 

 at the anastomosis, but still so that the apical margin 

 of the wing remains free ; pterostigma wanting; pos- 

 terior wings hyaline, with the anterior margin yellow. 

 App. sup. $ small, triangular, not projecting beyond 

 the extremity of the abdomen, closely applied upon 

 the App. infer. 



On the whole, in form and coloring, this species is very 

 similar to L. vittatus, and especially to its variety 

 L.flavus, in the colouring of the anterior wings. L. 

 centralists, however, easily distinguished by the form, 

 and length of the fifth apical cell, and by its more 

 dense clothing of yellow hair upon the anterior wings ; 

 in L. vittatus, also, the brown dash on the apical 

 margin is always below, and in L. centralis always 

 above, the brown line. 



Varieties in which the brown dashes break up into 

 numerous larger or smaller, and sometimes much 

 darker spots, which may then also occupy the entire 

 apical margin, are described as L. nebulosa, Ramb. ; 

 and L. ustulata, Steph. 



Length 4^ lin. ; exp. 8 lin. 



Hab. London ; not rare in June and July.
